With the latest patch, Westwood has added in a toggle for the driver.If -- and only if -- the server allows non-driver gunners, the driver can now override that. That means the driver can CHOOSE whether the 2nd person can control the turret. It is toggled by pushing a key, "Q" by default.
However, if the server has the option "Driver always gunner" turned on, this new feature will not do anything.
If you want to remap "Q" to another key, open C:\Westwood\Renegade\Data\config\input01.cfg and look for the line:
VehicleToggleGunner_Primary=Q_Key
Simply change the "Q" to another key (but make sure you leave the "_Key" part in).
